National Environmental Field Activities Program (NEFAP) Executive Committee

The purpose of the National Environmental Field Activities Program (NEFAP) Executive Committee is to establish and implement an accreditation program for field sampling and measurement organizations (FSMOs).

The TNI Standard for FSMOs is modeled after ISO/IEC 17025:2005 "General Requirements for the Competence of Testing and Calibration Laboratories." TNI Standard Volume 1 is the FSMO Competency Standard, which is the same international standard for fixed laboratories. TNI Standard Volume II is the FSMO Accreditation Body (AB) Requirements to Accredit FSMOs. The AB Standard is based on ISO/IEC 17011:2004 "Conformity Assessment - General Requirements For Accreditation Bodies Accrediting Conformity Assessment Bodies."

Note: On June 9, 2010, this committee was renamed the NEFAP Executive Committee to reflect a change in the TNI bylaws. Documents such as meeting minutes may show the previous name of this committee, NEFAP Board.
